I am at the final step of a Save function and I need help figuring out how to structure the data back into the format of my CSV so that I can write over the original. This is a link to my other code/post helping me get to this point: StackOverflow, first question I have separated the records and changed the right values but now I need to join the records back in the same format as the CSV file to then write over the original CSV.

Here is my code:
